摘要： A mass spectrometer is provided having a plurality of analyzers and including at least one magnetic sector analyzer and, typically, an orthogonal-acceleration time-of-flight mass analyzer. Bypass means are provided so that by switching of the direction of the ion beam, the magnetic sector analyzer may be bypassed and the time-of-flight analyzer used either to analyse the beam of ions from the source or daughter ions produced by fragmentation of that beam.

摘要： A mass spectrometer (MS) that is adapted to allow rapid gas-phase hydrogen/deuterium exchange (HDX) labeling of ions in one or more traveling wave ion guides (TWIGs) with or without ion mobility separation. The addition of isotopic labeling by gas-phase HDX offers a sensitive alternative dimension for conformational detection, which enables high resolution detection of gaseous conformations based on shape and surface reactivity. Gas-phase, isotopic HDX labeling or “curtain” labeling, can be performed by infusing a reactive, isotopic labeling gas, e.g., ND3, into one or more of the traveling-ion wave guides (TWIG) in the MS. Analyte ions retained in the potential wells of a traveling wave generated by one or more of the TWIGs can be isotopic labeled at adjustable gas pressures. Labeling times can also be controlled by adjusting the speed of the traveling wave and can be performed within milliseconds of ionizations, probing protein conformations present in solution.

摘要： The invention provides a mass spectrometer for the analysis of a sample dissolved in a fluid, and in particular a spectrometer for the analysis of high molecular weight compounds in the eluent of a liquid chromatograph. The fluid to be analyzed is at least partly vaporized and sprayed into the cathode dark space of a glow discharge. Ions characteristic of the sample are extracted from the discharge and subsequently mass analyzed. conveniently, spraying into the cathode dark space is achieved by making the cathode electrode of the discharge comprise the spraying means through which the fluid is sprayed. Little fragmentation of the high mass ions is caused by the process, and the invention extends the range of compounds which can be analyzed in comparison with similar prior art thermospray type mass spectrometers.

摘要： An electrospray and/or atmospheric pressure ionization mass spectrometer includes an evacuated chamber, a sampling region within which is maintained a pressure greater than in the evacuation chamber, a sampling orifice that communicates between the sampling region and the evacuation chamber, and a mass analyzer that receives charged particles along a first axis through the sampling orifice from the sampling region into the evacuated chamber. A plurality of charged-particle jet generators, each having an associated jet axis, are adapted to be alternatively, selectively aligned such that a respective jet axis intersects with the first axis associated with the mass analyzer. This alignment is performed through the use of a hollow member which functions to guide charged particles through the sampling orifice to the evacuated chamber and, subsequently, to the mass analyzer.

摘要： The invention typically provides a double focusing mass spectrometer comprising an ion source (55), an ion momentum analyzer (56), a multichannel detector (58) and a multielectrode electrostatic ion-energy analyzer (57), wherein the energy dispersing field is generated by arrays of electrodes disposed in groups above and below the ion beam. By appropriate selection of the potentials applied to the electrodes, the focusing properties of the analyzer can be changed, allowing different extents of the mass spectrum to be accurately focused on the face of the detector (58) as it is tilted by the actuator (61) at different angles to the ion beam (64) emerging from the analyzer (57). This enables the spectrometer to simultaneously record either a small part of a mass spectrum at high resolution or a larger part at a lower resolution. Alternative arrangements of the detector which allow a similar result to be obtained are also disclosed.
